When it comes to wooden fencing, rot is often an issue that can cause considerable damage to the appearance and integrity of the structure. As well as making the wooden panels look unsightly, rot can reduce the strength of a fence, causing it to break. Typically, wooden fences will be constructed outside in contact with soil and rain, making rot something of an inevitable issue if the wood is left untreated. Wet rot is the most common type of rot for fences, and other outdoor timber structures in the UK, as the level of moisture from rain and damp earth create problems such as cracking and softening the wood, fungal growth and musty smells. Luckily, there are a number of ways in which you can protect your fence from rot and stop it spreading:

Choosing the Right Material

When selecting a wood type for your fencing, there should be more to consider than the aesthetics, as certain types of wood are better at withstanding damp conditions than others. Pine, for example, is quite prone to rotting, whereas woods such as juniper, cedar and redwood are more rot-resistant. Other ways of reducing rot through material choice can be achieved by using concrete footing or fence posts, as this will reduce or eliminate contact between the wood and the ground, stopping the wood from absorbing moisture and rotting. 


Slope Fence Post Footings

Fence post footings made from concrete should be slightly sloped, directed away from the wood panels. This will direct any rainfall away from the fence, stopping water from pooling near the wood and causing damp or rot problems. 

Treat Your Fence

One of the key ways to help protect your fence from rotting is to ensure that the wood is treated. Coating each panel and post thoroughly with wood preservative will help to seal the wood, protecting it against water damage. Waterproofing your fence will also help to stop the organic growth of mould, moss and fungi, without the need for fungicides, making timber waterproofing a safe option for use in gardens, where the wood may be in contact with plants and animals. 


Replace Rotten Wood

If you have a fence in your garden already which is suffering from rot, some sections of the wood may need to be replaced if it is badly affected. Rot spreads quickly, so it is best to act fast replacing rotten wood. New wood panels will need to be treated with a water repellent coating to protect against rot in the future. As they have the most contact with the ground, fence posts are the most likely area of the fence to become rotten, so checking these are thoroughly coated with wood preservative is important. 

Sweep Garden Debris Away

Garden debris, such as damp leaves, plants or grass that are close to the fence can be the cause of a rot problem as the dying foliage begins to decay. Giving the area near your fence a good sweep every once in a while to clear away any old garden waste will be extremely beneficial.
